Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Christmas Plum Pudding, Royal
Ingredients
Directions
Prepare the mixture
In a bowl, combine the bread crumbs, flour, and salt.
Add the suet, raisins, currants, candied peel, almonds, and sugar. Mix well.
Stir in the whisked eggs, milk, baking soda, and brandy until just moistened.
Cloth and boil
Prepare a pudding cloth by boiling it in water, wringing it dry, and flouring it.
Place the pudding mixture in the cloth, tie securely, leaving room for expansion.
Boil the pudding in boiling water for 4 hours or steam for 5 hours.
Ensure to add boiling water as needed during cooking.
After cooking, hang the pudding in the cloth to cool.
Serve
To serve, boil the pudding for 1 hour to heat through.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the mixture and set into a firm, sliceable structure when cooked.
- All-purpose flour
- Provides the main structure that holds the dense, moist pudding together.
- Stale bread crumbs
- Absorb liquid and add body, giving a tender rather than gummy texture.
- Suet
- Adds fat that keeps the pudding moist and rich as it cooks.
- Baking soda
- Releases gas that lightens the pudding and helps it rise.
- Muscatel raisins
- Add concentrated sweetness and chewy moisture throughout the pudding.
The step that matters
Leave room for expansion and keep the water boiling. The pudding swells as it cooks, so the cloth must be tied loosely enough to allow it. Topping up boiling water keeps the temperature steady, so the pudding cooks evenly rather than turning heavy or sodden.
Swap the currant
How well each one fits the dish's main ingredients (bread, flour, raisin, almond, sugar, egg, milk):
- Vanillafits better
- Figfits better
- Datesfits better
- Currantthe original
Fit is the average pairing score against bread, flour, raisin, almond, sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
